IMPROVEMENT IN PEN AND PENCIL CASES.

Specification forming part of Letters Patent No. 169,0 [2, dated October 19, 1875 application filed August 6, 1875.

To. all whom it may concern Be it known that I, WILLIAM A. LUDDEN, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Pen and Pencil Cases, of which the following is a specification Pen and pencil cases have been made with an extension-tube at one end, by the revolving of which a cylinder containing a screw slot is revolved for moving in and out an everpointed pencil. In this construction the screwtube is liable to become obstructed by dirt and other foreign substances that enter through the slit in the outer case that the pins pass through which connect the slide with the pen-holder.

My improvement is made for inclosing the screw-tube and keeping itolear; and consists in a tube within the case inclosing the screwtube, and extending to the top of the case and terminating as a collar, by which the inolosingtube and screw-tube are revolved to project or retract the pencil. In this pencil-case the point is projected or retracted regardless of the extension-tube.

In the drawing, a longitudinal section of the improved pencil-case in an enlarged size is represented.

The ever-pointed pencil a is of ordinary character, and contains the device for projecting the lead. The cylinder containing the mechanism of the pencil slides freely in the stationary tube 12, that is connected at one end with the end piece 0 of the pencil-case, and this tube bis slotted longitudinally for the pin e that projects from a, and passes also through the slot of the screw-cylinder d that surrounds the tube 12, and hence the ever-pointed pencil will be projected or retracted by the revolution of the screw-cylinder d. An inclosingtube, i, is attached at one end to a collar around the screw-tube d, and at the other end this tube terminates with the collar 1, so that this tube t' can be easily revolved by grasping the collar, and, in so doing, the screw-cylinder will also be revolved and the pencil moved. The exterior ornamental case 9 is at a sufficient distance outside the tube 13 to allow the pen-holder h to be introduced between them, and the case g is slotted, and the pencilholder is connected to the ring a that surrounds the case, and by which the pen is moved, as usual. The end of the case is open at the place where the pen and bolder are projected, as in other cases of this character.

The extension-tube 0 slides freely within the tubei and collar 1, and may or may not al- WM. A. LUDDEN.
